SHOE-HEEL.

Application filed May 1, 1916.

VTo all 'whom t may concern Be it known that I, Jnr'iHi-x C. TA'rUM, la citizen of the United States of America, residing at Richland, in the county of Stewart and State of Georgia, have invented newV and useful Improvements in Shoe-Heels, of which the following is a speciiication.

rlhe present invention relates to improvements in shoe heels, and is designed particularly for the purpose of constructing the heel of the shoe with movable parts whereby friction is provided for the purpose of generating heat.

Thus the invention contemplates the use in the slice heel of movable friction members for generating heat so that the inclosed foot may be warmed, and the action of the movable parts is caused by the act of walking, upon the part of the wearer ofthe shoe equipped with my novel form of heel.

The invention consists in certain novel combinations and arrangements of parts for generating the heat for the purpose above indicated and incidentally for providing the shoe with a resilient heel portion as will be described.

In the accompanying drawings I have illustrated one complete embodiment of the physical adaptation of my invention constructed according to thebest mode l have so far devised for the practical application of the principles of my invention.

Figure l is a perspective view of a shoe equipped with my novel form of heel. Fig. 2 is a View of an enlarged heel, showing the heel and the device of my invention, in section. Fig. 3 is a partial top plan and partial sectional View of the heel.

The shoe 1 may be of any shape or style, but for convenience of illustration I have shown a convenient form of button shoe provided with the heel 2, which to all external appearances is the same shape and proportionate size of the usual heel, while the outer sole 8 and inner sole 4 are of usual character or type.

The heel portion is made hollow, or bored out in suitablemanner to convert it for use according to my invention, and in the recess or cut out portion of the heel the cup 5 is embedded. This cup preferably conforms to the shape of the heel, is open at the top and provided with a lateral, top flange 6, and the cup is secured to the heel by passing nails 7 through the flange whichfis perfo- Speccation of Letters Eatent.

rated for the purpose. This cup is preferably of hard rubber, or of other material which is a poor conductor of heat and formed with a hard surface.

1Within the hard rubber cup a plunger 8 is adapted to reciprocatevertically, and it is the re'ciprocation of this plunger within the hard rubber cup which causes the friction to generate the heat. The plunger 8 is made up of a metal cup 10, inverted, and open at the bottom. Preferably the cup or plunger body is made of aluminum for its strength and lightness, but other sheet orv similar metal may be used for this purpose. The upper end of the plunger is closed by the top plate 9 and the overhanging edge of this plate is notched or cut out at intervals as indicated at ll to provide orifices or openings to facilitate the movement of heated or warmed air.

A central screw threaded, integral7 boss 12 projects from the top plate 9 within the plunger body, and this boss is devised to receive the screw 13 which holds the bottom plate 14 of the plunger, and this plate or head secures the friction band 15 to the plunger body. rlhe band 15 is preferably of leather and extends around the plunger body, being held between the edge of the top plate 9 and the removable bottom plate la. By means of the screw 18 and plate 14, the friction band 15 may be distended, or by loosening the screw and head, the band may be permitted to contract, thus increasing or decreasing the friction between the band of the plunger and the walls of the cup 5.

To automatically cause the plunger to reciprocate I utilize the spring 16 located betweenthe lower head-16 o-f the plunger and the bottoni of the cup 5. Thus when the pressure from the heel of the foot is on the plunger as in the position of Fig. 2, the plunger is forced down. This occurs when the wearer of the shoe is walking and puts his heel on the ground. When the walker rises upon his toes the weight of the heel of the wearer is lifted from the plunger and the spring 16 forces the plunger upwardly. These alternate downward and upward movements of the plunger, which fits with a frictional contact within the walls of the cup 5, cause friction togenerate heat and the heat from the friction passes up throughout the shoe warming the inclosed foot. For

ventilation in warm weather, the opening AT17 is provided, but in cold weather this opening is closed by the spring turn button 1S pivoted at 19 to the front Wall of the heel.

It will be understood of course that shapes other than those illustrated may be utilized, and the invention may be changed in minor details, Without departing from the spirit of my invention.

That l claim is l. A hollow shoe heel having a cup Xed therein, and a resiliently supported reciprocable member' in the cup provided With a detachable portion in frictional engagement V15 `with the Walls of the cup, said member being .adapted to reciprocate as the wearer of the shoe Walks.

2. A hollow shoe heel having a cup Xed therein, a .reciprocable member provided with a friction band to engage the Walls of said cup, and a Spring for holding said member in raised position.

V3. A hollow shoe heel having a cup iixed therein, a reciprocable member provided with a friction band and a retaining head therefor', and a spring under said head for holding the memberin raised position.

In ,testimony whereof l aiix my signature.
